Creative has built the best soundbar ever made. It’s probably better than what any other soundbar manufacturer has dared contemplate. It’s an audio system that’s so over the top that calling it a mere soundbar is an injustice. But I’ve yet to hear any soundbar at any price—and this one costs nearly six grand—that delivers the theater audio experience as effectively as a component system, and the X-Fi Sonic Carrier is no exception. 

My play on words in the title of this review is thus a left-handed compliment. The Sonic Carrier’s price tag isn’t exorbitant when you take into account all its hardware, feature set, and capabilities. This speaker is an embarrassment of riches in that regard. The absurdity is that all that high-end technology is packed into a soundbar that by the laws of physics cannot deliver a surround-sound experience that’s as immersive as a lower-priced component home theater system. (At the time of this review, Creative was discounting orders for delivery to the lower 48 states to $3,999, plus $150 for shipping.) 

This review explores the X-Fi Sonic Carrier in substantial detail. If you just want my one-sentence opinion, scroll to the bottom of the page.

Look ma! No wires!

A soundbar like the Sonic Carrier, however, offers one huge advantage over component audio systems: A dramatic reduction in the number of cables you need to deal with. I was in the process of reviewing Focal’s $1,299 Sib Evo Dolby Atmos speaker array with a $799 Onkyo TX-NR737 A/V receiver when the Sonic Carrier arrived (I decided to push the Focal review to a later date).

Even though the Sib Evo incorporates the Dolby Atmos height speakers into the same cabinets as the front left and right speakers, I still had to measure, cut, strip, and route seven sets of speaker wire, plus one RCA cable for the subwoofer, to set up that configuration. The only wires the Sonic Carrier needs are the ones from your sources (e.g., an HDMI cable from your Blu-ray player), and the HDMI cable to your TV. You do temporarily hardwire the subwoofer to the soundbar, but that cable is removed after the initial setup.

The Sonic Carrier is a hulking beast of a speaker. Should you decide to use the provided mounting brackets to hang it from a wall, you’ll want to be certain that it’s anchored to the studs behind your drywall with very long screws: This monster measures 59.9 inches wide, 5.9 inches deep, and 3.8 inches high. Its frame is fabricated from anodized aluminum, but you’ll still need two people just to remove its 35.3-pound bulk from the box.

sonic carrier calibration Michael Brown / IDG

The X-Fi Sonic Carrier relies on the mic in your mobile device for room calibration. 

Creative describes it as an 11.2.4 speaker configuration, which is a little different than how Dolby classifies Atmos systems. The .2 in Creative’s figure represents height speakers, and the .4 indicates the number of supported subwoofers (the system comes with one, and you'd need a room the size of a stadium to need more than that). Dolby would describe this as an 11.4.2 system.

In any event, each of the Sonic Carrier drivers are independently controlled by an EAX 15.2 digital signal processor (DSP) to produce 16 directional outputs (nine front-firing, two side-firing, four up-firing, and one for low-frequency effects or LFE). Each driver is powered by a discrete Class-D amplifier. The amps in the soundbar itself produce a combined 400 watts RMS, while the sub is outfitted with a pair of 300-watt Class-D amps.

Independent driver control might be important, because you’ll calibrate the system for the specific acoustic characteristics of your room. It’s hard to evaluate the effectiveness of that calibration, however; the fact that it relies on an app running on—and the microphone in—your mobile device casts a shadow over the concept. Dedicated A/V receivers (from midrange on up) have onboard calibration systems that utilize custom microphones, so the calibration software is tuned to the hardware and knows exactly what to expect.

By the same token, Sonos’ Trueplay speaker-tuning software runs on mobile hardware, but the company offers it only on iOS devices, because it knows all about the capabilities of those mics. It’s impossible for any manufacturer to know and plan for the capabilities of the myriad mics in the fragmented environment of Android hardware

Side-firing 2.25-inch aluminum-alloy full-range drivers mounted inside the Sonic Carrier’s left and right end caps handle surround-sound duties. In a traditional 5.1 home-theater speaker system, this would be handled by discrete speakers positioned near your listening/viewing area. The front-firing speakers for front-left, -right, and -center consist of three 1-inch aluminum-alloy dome tweeters and six 2.75-inch, aluminum-magnesium mid-range cones. In a conventional home-theater system, you’d have a stereo pair for left and right and a third dedicated speaker for the center.

Full-range speakers in the soundbar's end caps handle surround-sound duties.

A pair of 1-inch aluminum-alloy tweeters, along with two more 2.75-inch midrange drivers, fire up from the top of the speaker, bouncing height audio cues off your ceiling. In a conventional 5.1.2 system, these speakers would be mounted in your ceiling firing down (and a 5.1.4 system would add a pair of height speakers to the back of the room).

It wouldn’t be a home theater system without a subwoofer, of course, and Creative really goes the extra mile on that score. The X-Fi Sonic Carrier ships with one equally massive powered sub, but it’s capable of pairing with four of them—wirelessly, no less (additional subs cost $2,199 each; $2,699 for the piano-black finish). As I mentioned earlier, you need to connect the components with a cable during the initial installation, but you remove it once pairing is complete. The sub is 22.9 inches high, 20.9 inches wide, by 12 inches deep. Make sure the friend who helped you place the soundbar sticks around long enough to help you place the sub: It weighs 60 pounds.

The controllable multi-colored LED light ring on the massive subwoofer is one of the X-Fi Sonic Carrier's more gratuitous features.

The sub consists of a pair of 300-watt RMS Class-D amplifiers, with each one driving a 10-inch, paper-cone-with-rubber-surround high-excursion woofer. The woofers are mounted in an MDF enclosure and arranged in a push-push configuration (i.e., the woofers are mounted back to back). They’re mated to a pair of flared ports. Creative reports frequency response of 150Hz to 40kHz for the main unit, and frequency spot of 25- to 150Hz for the sub.

I/O city

Most better-quality soundbars have at least two HDMI inputs and at least one HDMI output with ARC (audio return channel, for sending your TV’s audio back down the cable to the speaker). They’ll also support at least one analog audio source and be outfitted with at least one digital audio input (typically of the optical variety).

The X-Fi Sonic Carrier has four HDMI 2.0a inputs, each of which supports HDCP 2.2 copy protection, and one HDMI 2.0a output with ARC. There are two Toslink optical inputs for digital audio sources, two sets of analog stereo line-level aux inputs (RCA), one analog stereo 3.5mm aux input, two ¼-inch inputs to support dynamic microphones for karaoke, and one set of analog stereo line-level outputs (RCA).

Creative thought of everything you might want, except for coaxial digital audio input/output and a 12-volt trigger for something like a video projector screen.

Need to connect even more music sources? There’s one SD memory card slot, three MicroSD card slots, and two USB 2.0 ports for hosting thumb drives and/or portable hard drives (storage can be formatted FAT32 or NTFS). A third USB port is dedicated to providing power. Should you want to charge your smartphone or tablet, this port puts out a full 5 volts and 2 amps. The two mic inputs, one of the 3.5mm aux inputs, one of the HDMI inputs, one of the USB ports, the four memory card slots, and the USB power port are in the front of the unit, discreetly hidden behind a drop-down panel, where they’re conveniently accessible for temporary connections.

This hidden drop-down panel in front conceals (from left to right) two 1/4-inch mic inputs, a 3.5mm analog aux input, an SD card slot, three microSD slots, a USB data port, a USB charging port, and an HDMI input.

The Sonic Carrier has a dual-band 802.11ac Wi-Fi adapter onboard, as well as a gigabit ethernet port in back. You can also stream music via Bluetooth 4.1, with support for the aptX (but not the aptX HD) codec. If you set up the speaker on a console in front of your TV and discover that it blocks the TV’s infrared receiver, you can plug in an IR blaster to pass the signals from your TV’s remote through from an IR receiver on the front of the speaker.

The brains powering the brawn

A 64-bit quad-core 2GHz ARM Cortex A-53 CPU with access to 2GB of RAM and 16GB of flash storage enables the Sonic Carrier to use the Android 5.4 (Lollipop) operating system. The CPU is supplemented by a Mali T720 graphics processor capable of supporting 4K Ultra HD video (3840x2160), but it’s limited to a maximum refresh rate of 60 frames per second. You can also plug a Chromecast or Amazon Fire TV Stick into the soundbar, but I didn’t evaluate that feature.

Incoming stereo audio signals are fed to a quad-core X-Fi digital signal processor (analog signals are converted to digital, first). The X-Fi chip upscales these streams to 24-bit/192kHz resolution and then splits them into a 7.1 stream (front left, right, and center; height left and right; surround left and right; and low-frequency effects). The digital audio output from the processor decoding Dolby Atmos (and with an upcoming firmware update, DTS:X) is sent to the X-Fi DSP, too, where it’s also upscaled to 24-bit resolution. From there, the audio signals are sent to a second DSP that subjects the audio to Creative’s various effects algorithms (if you want them).

This diagram shows the paths audio, video, and data signals travel through the X-Fi Sonic Carrier.

This second chip also splits the digital audio into 16 bitstreams—one each for each driver in the soundbar and one for the subwoofer. These signals are routed through a pair of digital-to-analog converters, amplified, and output to the midranges and tweeters in the soundbar. Low-frequency effects (LFE) remain in the digital domain, so they can be sent to the wireless subwoofer where they’re converted to analog and amplified.

A smallish flip-up LCD displays brief status messages, but the graphical user interface that’s displayed on your TV via HDMI is much more useful. The GUI looks very basic—almost crude—but it is extremely responsive. The provided infrared remote has a D-pad that can be used to select a grid of icons with multiple button presses, or you can activate a mouse-like function and move the cursor by holding the D-pad in the direction you want it to move. Creative also gives you the option of plugging in a USB dongle for a wireless QWERTY keyboard.

This small hinged display reports the Sonic Carrier's current status. 

The company sent one equipped with a trackpad with my review unit and I found it extremely helpful, especially for typing in URLs, for search, and for entering login credentials for online services. The full Chrome browser comes pre-installed, along with Netflix and YouTube for video streaming, and Spotify, Tidal, Deezer, and TuneIn Radio for streaming music. You can load third-party apps from the Google Play Store, but Creative says its primary intention in using Android is to provide the foundation for its user interface and Creative’s own apps.

You can control the Sonic Carrier three ways, and you’ll probably find yourself using a combination of all three at once. You can press physical buttons on top of the speaker to control most of its functions: switching input sources, adjusting the volume, controlling media playback, and lots more—including controlling the LEDs on the subwoofer. A 33-button infrared remote offers the same functions plus many more, including a mouse function for interacting with the GUI. At this price, I expected the remote to have backlit buttons. It doesn’t and is therefore useless in a darkened room. Lastly, you can use the mobile app, which is available for Android and iOS devices.
